Claims. (01. 91-47) My invention relates generally to machines forforming frusto-conical or conical; tapering or cylindrical jackets, andin particular it has for its object to provide a new and improvedmechanism for applying adhesive to the jackets while they are held haton the conveyor carriages.

A further object is to provide suchmechanism, operating in harmony withthe other mechanisms of the machine, to apply the adhesive while thecarria e is moving past the glue applying station.

Another object is to provide a continuously moving glue applying meanswhich includes intermittently operated applicators and means to effecttheir operations in time with the movement of the blank carriage.

Other objects will in part be obvious and in' part will be pointed outhereinafter.

To the attainment of the aforesaid objects and ends the invention stillfurther resides in the novel details of construction, combination andarrangement of parts, all of which will be first fully described in thefollowing detailed description, and then be particularly pointed out inthe appended claims, reference being had to the accompanying drawings,in which:

Fig. 1 is a front elevation of so much of the jacket forming machine asis necessary to illustrate the position and relation ofthe adhesiveapplying mechanism proper to the carriages and conveyor.

Fig. 2 is a side elevation of the turret unit.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2.

Fig. 4. is an edge view of one of the applicators.

Fig. 5 is a side elevation of the same.

Fig. Sis a side elevation showing the other side of the applicator.

In the drawings, in which like numbers of reference indicate like partsin all the figures, the numerals used are the same as those used toindicate the same parts shown in my application Ser. No. 379,727, filedFebruary 19, 1941, of which this application is a division.

In general, the jacket forming machine includes a frame havinglongitudinal beams 4 and 5 and uprights 3. An endless chain II has linkbrackets 22 on which the bases 23. of the jacket of the presentinvention, a detailed description of the same is superfluous in thisspecification.

By referring now more particularly to Figs. '1, 2 and 3, it will beseenthat in an upper bearing I50 and a lower bearing I68 is mounted avertical shaft I5I to which is secured the hub I52 v of a turret thatcomprises the said hub, the upperand lower discs I53, I54 respectively,and the parts carried by thediscs. Such parts consist of four sets ofdauber devices arranged radially 90 apart. Each dauber device consistsof two rods I55 passing vertically through bearing holes in the discsand connected together at the top by a cross-head or plate I56 on whichis secured a bevelled block I66. Beneath the disc I54 the rods I55 carrystop collars I51 and angle heads I62, to which heads the daubers I63(rubber or other suitable material) are mounted by means of clamp platesI64 and screws. Each dauber I63 has one or more glue spotters I65.

The cross-heads I56 are vertically adjustably held by cotter pins I60and the lower disc I54, and tend constantly to raise the daubers.

A fixed cam I6! is engaged by the bevelled blocks one at a time as theturret turns in order to depress the daubers onto the rollers I95 of theglue pot I92. The pot I92 is removably held on a bracket I90 by clampscrews I9I.

The shaft I93 on which the rollers I95 are mounted is driven from theconveyor drive shaft (not shown). The amount of glue on the rollers I95is regulated by an adjustable slide or plate I96 whose inner edge liesadjacent the rollers I95, the space between that edge and the rollersgoverning the thickness of the film of glue'on the tops of the rollers.

At its upper end the shaft I5I has a bevel gear I69 that meshes with abevel gear "I on a cross shaft H0. The shaft H0 is driven from acontinuously rotating rotary shaft 243 and bevel gears 244.

- There is also a spur gear I'II secured on shaft I10 to mesh with apinion I'I8 on a stub shaft I19. On this stub shaft is mounted a cam Iwhich cooperates with a cam-engageable nose I83 on a rocker arm I82 thatis pivoted to a support I SI and is connected by an adjustableconnecting rod I88 with an arm I84 that is pivoted at I85 to a suitablesupport and carries a tappet I81 to engage the bevelled blocks I66 atproper times, as will later more fully appear. I86 is an arm adjustingscrew.

Mounted behind the turret is a U-shaped bar I99 whose ends 200 areforked to receive the stud bolts 3M that adjustably secure the supports20I to the bar. The supports 20 I carry one or more grooved discs 202around which taut wires 203 are passed and have their ends anchored asat 204. These wires lie horizontally across the paper blanks on thecarriages as the carriages pass the turret at what might-conveniently betermed the glue-applying station of the machine.

Just beyond the glue-applying station is a mandrel wiping deviceconsisting of a. bracket 2'05 carrying a wiper 205. A the mandrels passthis wiper they are being forced outwardly (forwardly) under the wiper,which wiper is so positioned that the entire length of the flat surface56 will be wiped clean.

Operation wheels l95 bybeing for an instant pressed down in contact withthe fixed cam 161. When a dauber comes into proper position over acarriage so as to be directly over and line up with the righthand sideof the blank on the carriage, the lever I84 is forced down for aninstant and tappet I81 engages the bevelled block I 56 of that dauber tostamp the glue on the paper.

The wires 203 are stretched taut and prevent the blanks from sticking tothe daubers I64 as the daubers lift up after stamping the glue on theblanks.

After the glue has been applied the blanks are applied to the mandrelsand brought to shape for use in any suitable way, preferably in themanner and by the means disclosed in my original application aforesaid,but as that means is not a Dart of the present application, detaileddescription thereof is not necessary to an understanding of the subjectmatter of this application.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought that the construction, operationand advantages of the invention will be clear to those skilled in theart to which it relates.
